About The Thing:

Just beyond the 3rd Flatiron - a classic climb.

Approach:

Park at Chautauqua Park and head up the Kinnikinik road to the
Bluebell Shelter. Take the Royal Arch Trail, continuing toward the
Royal Arch when the trail forks. (The right branch leads towards the
3rd Flatiron.) The trail crosses Bluebell Canyon and climbs steeply
until Sentinel Pass. Head due west up hill at this point off trail and
bear north until you find the base of the Thing.
